Doosan Attachments

Gear up for your job with the hard-working line of Doosan attachments. We build our own tough breakers, clamps, plate compactors and a wide array of bucket types and sizes. All of them are built to Doosan machine specifications for superior reliability and performance.

Performance

Take the controls. For every dollar you spend on your equipment, Doosan gives you more. Powerful hydraulic forces with high horsepower and torque characteristics bring superior production. Low-emission engines utilize high pressure common rail electronic fuel injection for superior top-end performance and a strong low-end torque rise. Powerful arm and bucket forces on our excavators allow you to move dirt with ease. Performance is what it’s all about; Doosan delivers what you need — and then some.

One-Touch Power Boost

The convenient button on the right-hand joystick provides momentary increased hydraulic power to break through hard ground and other tough digging conditions.

Electronic Power Optimizing System (EPOS)

The EPOS works in conjunction with the engine’s ECU to monitor and optimize machine performance for increasing productivity while reducing fuel consumption.

Four Power Modes

Selectable power modes give you more control over your excavator’s performance. Manage the balance of fuel consumption and machine power to your liking, based on your working conditions. Power+ mode delivers the fastest workgroup speeds to save more time when loading trucks. Top digging performance delivers extra power for digging in hard ground and other tough conditions. Power mode provides excellent power and superior performance for tough digging and heavy lifting. It also provides quick truck loading and fast travel speed to save time. Standard power mode optimizes your fuel consumption and delivers high performance in everyday digging, grading and lifting. Economy mode reduces fuel consumption for low-demand applications and slows down machine movement, which is handy for fine digging, light grading conditions and jobsite conditions that require extra precision.

Smart Power Control (SPC)

SPC consists of two systems that work together to improve efficiency while maintaining productivity and is controlled by the engine control unit (ECU). Each of the four power modes will function with SPC engaged or disengaged; however, SPC can only be active in the digging work mode.

Variable Speed Control

Variable speed control reduces engine RPM during low workload requirements, like during the swing portion of a dig cycle. This reduces the energy used to perform a task and improves fuel efficiency by up to five percent.

Auto Idle

To reduce noise, improve jobsite communications and save fuel, the standard auto idle feature idles your engine automatically when machine functions are not used for a few seconds. When you move the controls, the excavator automatically returns to your previous throttle setting.

Auto Downshift

When turning, pushing and maneuvering, auto downshift reduces the hydraulic flow to the drive system – improving machine responsiveness and controllability. When the load decreases, the excavator automatically shifts back into high range.

Auxiliary Mode Switch

If needed, an auxiliary mode switch allows you to finish a job or move your excavator to a convenient location for service.

Selectable Work Modes

Four unique work modes enable you to tailor your excavator’s performance to the work in front of you. Two modes recalibrate machine power for digging or lifting, while two change the auxiliary hydraulic flow for specific types of attachments. Just change a few settings with the LCD display panel to quickly optimize performance and protect your hydraulic components.

Lifting

The increased pump torque, low engine RPMs and automatic power boost provide extra muscle when lifting materials – like pipe or concrete barriers.

Intelligent Floating Boom

The boom float setting allows the boom to move freely with the contours of the ground. Ideal for finishing work, operators can focus on the arm and bucket. When engaged, the boom does not utilize hydraulic flow, increasing efficiency and productivity by saving fuel and improving cycle times.

Split Cooling

The split cooling system allows the oil cooler and radiator to operate independently to optimize the hydraulic system and engine temperatures, even in severe working conditions. The system increases cooling capacity while protecting and extending the life of engine components.

Variable Speed Hydraulic Cooling Fan

The hydraulic oil cooler on the DX300LC-5 and larger machines utilizes the variable speed cooling fan. The speed of the fan changes as required by the demands of your excavator. In tough, difficult applications, the fan runs faster for optimized cooling. When you’re in lighter duty conditions, the fan runs slower to increase efficiency and reduce noise.

Oil and Filter Life

Easily review the hours since the last maintenance for oils and filters. Your machine will remind you when each oil and filter needs replacing 10 working hours before service is due, assisting you in regular maintenance scheduling.

Hydraulic Attachment Management

Using the LCD screen, the operator can configure 10 different attachment presets: five each for 1-way and 2-way flow. Each preset selection can be matched to specific operational requirements of an attachment by limiting the maximum pressure and the minimum/maximum flow rate that is delivered to the attachment. When changing hydraulic attachments, the operator can easily select the appropriate preset to optimize machine and attachment functionality. Password protection functionality within the system discourages improper attachment preset selection for operators or rental users with limited understanding of hydraulic systems.

Recessed Drive Motors

Drive motors contained and recessed within the track width are protected from potential damage, resulting in more uptime.

Swing Torque

New Doosan models have an eight to 11 percent increase in swing torque that allows the excavator to swing uphill with ease — and improve backfilling performance. That means less excavation time per foot of trench.

D-Channel Frame Design

This innovative upper structure frame design adds strength to withstand more side shock, protecting your machine’s vital components.

Permanently Sealed, Lubricated Track Pins

Pin links on Doosan excavator tracks are permanently sealed. They never need greasing. That means you reduce your operating costs and increase your uptime.

Cast Ends and Pin Bosses

All the major pin points on the boom and arm are castings for extra strength in tough working conditions. Plus, additional reinforcement around the bosses and internal gussets gives a long life for the workgroup.

Centralized Arm and Boom Grease Points

Daily maintenance is critical – and it’s simple with the centralized grease banks on the arm and base of the boom.

Operator comfort

An operator can’t push performance to the limit if the cabin isn’t comfortable. Doosan knows how essential comfort is for its operators. From its great visibility to its deluxe, adjustable seat, Doosan cabins are easy to enter and exit, give you awesome standard features and bring superior comfort to the job.

Visibility

Sightlines to the work group are essential to operator performance. The large Doosan cabin provides an excellent viewing area on the front and side windows. When loading trucks or working overhead, the overhead window gives you great visibility above the machine. Narrow corner pillars, small window joints and a wiper mounted on the pillar – instead of on the glass surface – give the operator a better view. Sun shades on the front and top windows shield operators from the sun and reduce eye strain. It’s a complete visibility package that allows you to focus on your work instead of struggling to see it.

Quiet Operation

A complete, sound-isolating cabin seal reduces the noise inside the pressurized cab to an extremely low level. Compartmentalized components reduce noise output outside the cab. Even the cabin frame and seat are designed to absorb vibration and significantly increase operator comfort.

Easy-to-Read LCD Display Panel

An easy-to-read LCD display panel is placed within easy view for monitoring critical machine data as well as viewing errors, warnings and the rearview camera display. A big, seven-inch display also switches to a night view. The improved monitor allows operators to review key parameters while viewing the camera display.

Automotive Style Heat and Air Conditioning

High-capacity heating and cooling vents and an easy-to-control temperature keep you comfortable all year long. Automatic temperature control senses and adjusts to the temperature setting. A memory function returns it to your preferred temperature if you shut the machine off and restart later.

Automatic Belt Tensioner

A spring-applied automatic belt compensates for regular wear and maintains a constant tension on the engine accessory belt.

Heavy Duty Wear Plates

Ultra-hard and wear-resistant, these plates at the end of your arm and H-link extend the service intervals for your bucket pin-up point. By minimizing the tolerance between the bucket and arm, they maintain high breakout forces and ensure greater productivity.
